Shift Solenoid: Service and Repair

Solenoids-Shift. Torque Converter Clutch, Electronic
Removal

1. NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms can occur while the vehicle relearns its adaptive strategy. The customer needs to be notified that they may experience slightly different upshifts either soft or firm and this is a temporary condition and will eventually return to normal operating condition.

Disconnect the battery ground cable.
2. Raise and support the vehicle.





3. NOTE: If equipped, the transmission servo heat shield needs to be unclipped from the fluid pan rail and positioned out of the way for fluid pan removal.

If equipped, loosen the nut and position the heat shield out of the way.
4. Place a drain pan under the transmission fluid pan.
5. Drain the transmission fluid.





6. Remove the transmission fluid filter.
1. Remove the transmission fluid filter screw.
2. Remove the transmission fluid filter.





7. NOTE: Main control assembly does not need to be removed for solenoid service.

Remove wire loom guide and protector.
^ Carefully lift up on wire loom guide and protector and disengage the retaining pins from the solenoid clamps.





8. Disconnect the appropriate solenoid electrical connector.
1. Disconnect shift solenoids electrical connectors.
2. Disconnect the torque converter clutch (TCC) solenoid electrical connector.
3. Disconnect the electronic pressure control (EBC) solenoid electrical connector.





9. CAUTION: The TCC solenoid and converter modulator valve may pop out of its bore. This may damage the solenoid or converter modulator valve.

CAUTION: Shift solenoid (SSC) may pop out of its bore. This may damage the solenoid.

Remove the shift solenoids.
1. Remove the wire harness.
2. Remove the solenoid clamp screws.
3. Remove the solenoid clamp.
4. Remove the appropriate solenoid(s).

Installation





1. Install the new solenoid(s).





2. CAUTION: The solenoid clamp must be installed in the TCC and EBC solenoid grooves, shift solenoid pockets and the No. 204 plug.

Install the solenoid clamp.
1. Position the solenoid clamp on the main control valve body.
2. Install the solenoid clamp screws.





3. Connect the six solenoid electrical connectors.
1. Connect shift solenoid SSA, SSB, SSC, SSD electrical connectors.
2. Connect the torque converter clutch (TCC) solenoid electrical connector.
3. Connect the electrical pressure control (EBC) solenoid electrical connector.





4. CAUTION: Excessive pressure may break the retaining pins.

Install the main control valve body wire loom.
^ Align the retaining pins to the holes in the solenoid clamps and gently press in the main control valve body wire loom guide and protector.





5. Install the transmission fluid filter.
1. Install the transmission fluid filter.
2. Install the transmission fluid filter screw.





6. Install the transmission fluid pan.
1. Position a new transmission fluid pan gasket on the transmission fluid pan.
2. Align and install the transmission fluid pan.
^ Loosely install the transmission fluid pan screws.





7. Tighten the transmission fluid pan screws.
^ Use a crisscross sequence to tighten the transmission fluid pan screws.





8. Position the servo heat shield over the servos and clip it to the pan rail.
9. Lower the vehicle.

10. NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms can occur while the vehicle relearns its adaptive strategy. The customer needs to be notified that they may experience slightly different upshifts either soft or firm and this is a temporary condition and will eventually return to normal operating condition.

Connect the battery ground cable.
11. Fill the transmission to the correct fluid level and check for correct transmission operation
^ Use MERCON(R) V Automatic Transmission Fluid XT-5-QM or equivalent meeting MERCON(R) V specification.
